ADHD and productivity

Why do so many productivity apps fail people with ADHD? I’m genuinely curious because it seems like there’s no shortage of apps promising to help with focus, organization, and motivation, yet many people still struggle to stick with them. If you’ve tried any, what made you stop using them? Was it too complicated, too overwhelming, not engaging enough, or something else? I’d really love to hear your honest experiences and what an ideal app would look like for you.
